I would really like to know how to setup port forwarding at my work office. I need to get pcanywhere working, and i can't with this new router. Please help
It might be better if you setup a VPN (IPSec) on your Cisco router other then using port forwarding ,it could open holes on your network for attacks.
You can use something like SSH Sentinel or some other IPSec client on your windows machine to connect to your network. I would setup IPSec for road warrior. There are many docs on the web and Cisco site to help you with this task.

well, i thought about that, but my boss didn't want to settup VPN for whatever reason. He didn't want to change our current system. Before we got the cisco router, we had an ISDN router with port forwarding, and he wanted to keep it that way. And, even if i can convince him to go with the VPN, then i'd still like to know how to do it, just for person information.

Your not changing anything, it would give you more security , you can even map drives, print..etc.... without worring of being hacked., did you try searching on Cisco site for your answer. I found it on the Cisco site, but the url is to long of a post.

At home I have a DSL router that has IPSec and PPTP Server in the DSL router and I use IPSec all the time, thats how I connect to my LAN many many miles away and it work GREAT. My DSL also has a Stateful firewall and it configured right,so BYE BYE hackers..

I need to access this from the outside, i only have the one router, and i need to access our pcanywhere computer from home. How do i do that, cause VPN only works between 2 routers doesn't it? If i'm wrong please correct me, i'm VERY new to this whole deal

well, i just remembered, i have 3 pcanywhere computers running on the network that need to be accessed, and one of them has to be pcanywhere because it's a computer settup for our phone and copier system, and the people who set it up requere pcanywhere, so i still need to know how to use port forwarding.

You can do these three things
Computer to Network
Computer to Computer
Network to NetworkYour case, you would use computer to network and it's called road warrior setup, and it work GREAT. port forwarding is okay, but IPSec or PPTP is 100 percent better from a security point. You have the router already in place all you need to do is download SSH Sentinel for your windows client, BELIEVE ME IT WORK GREAT!!!!!!!!!

It does not matter , using IPSec is like connecting to your LAN as if your were right there at the office and you can still use PcAnywhere if you want to..

You don't need port forwarding , port forwarding is like this:
computer (port 80) ----> router(30000) it just re-maps the port to another port number, but it can still be scaned by hacker.

the point still stands though, those guys need to use pcanywhere to connect to their computer, and they won't want to use anything else. They're on a one track mind, but i think you have convinced me to use SSH Sentinel for everything else. And i searched cisco for port forwarding, and i couldn't find anything

does'nt port forwarding work like, i send a request for port 80 to my router's ip and then that request is forwarded to, in this case, the pcanywhere server?

pcanywhere i believe works on port TCP 5190? how do you want to forward that? give me an example?
0
i'm sitting at home with my pcanywhere... I set it up to connect to my routers ip address, and i want the router to forward that request to my pcanywhere host. I did that with the old router, and i'm pretty sure it's possible with this one, i just don't know how
0
they still can use pcanywhere or whatever the feel like, but it's how they are connecting to the network changes, like there at the office. all your changing is the method and how the connect, nothing else.

Thats not port forwrding, thats NATing or setting-up a static NAT..
computer(10.1.1.1)--->(router)12.1.1.1
Nat table
10.1.1.1 static nated to 50.1.1.3your nated pool is
50.1.1.1 -50.1.1.30 (example)POOR Design, not good way to do business...
0
yeah, i guess you're right, i would still like to know how to do it thought, but thanks for the tips, i'm pretty sure i'm going with IPSec for my stuff at least

I am telling you DON"T do that, you will be hacked.. I know of a company that did that and they were hacked.. I had to fix there problem, what a mess that was.

You have that good 1720 VPN router, USE IT , thats what it for . Setup a good firewall on the router and open ports for GRE and a few others which I don't remember off hand and setup a VPN(IPSec)connection. They can still use pcanywhere into your network with IPSec.

#conf t
#(config) ip nat inside source static 10.10.2.1 10.100.0.51where 10.10.2.1 is the pcanywhere pc's IP and 10.100.0.51 is the real IP.
That gives you a 1-to-1 NAT and little security.

can you do 'port forwarding' on overloaded nat?
e.g. internal network is 192.168.1.0/24, router external ip is 66.55.44.33, all the internal hosts are overloaded onto 66.55.44.33
can you then set it up so that someone connecting from the outside to port 5900 on 66.55.44.33 would be translated to internal host 192.168.1.13 port 5900?
thanks
